[RFC-v4 00/12] iSCSI target v4.1.0-rc1 series for .39-rc1

[Nicholas A. Bellinger]

From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>

Greetings all,

This is the forth RFC series of the RisingTide Systems iSCSI target fabric
module compatible with mainline target core v4 -> for-39 target infrastructure.

More information about iscsi_target_mod is available here:

http://linux-iscsi.org/wiki/ISCSI/configFS

This series contains the updated drivers/target/iscsi/ source tree for modern
mainline code based on feedback from Christoph Hellwig that has been recently
pushed into the lio-core-2.6.git/lio-4.1 development branch.  This includes
another round of iSCSI network portal changes to use proper Linux/Net code
w/ IPv6/IPv4 iscsi_np->np_sockaddr, conversion of iSCSI TX thread context
to use schedule_timeout_interruptible(), and the renaming the majority of
functions to use the 'iscsit_*' function prefix based upon hch's feedback.

This series is currently rebased against .38-FINAL using target core v4.0.0-rc7-ml.

The full RFC-v4 series for iscsi-target is available here:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/scsi-post-merge-2.6.git for-39-iscsi-target-v4

The changes from RFC-v3 -> RFC-v4 include:

*) Make iscsit_[free,stop]_session take conn_tmp reference first
*) Convert NPF_NET_IPV* flags to AF_INET*
*) Add missing unlock for iscsi_get_np
*) Convert iscsi_target_tpg.c to use 'iscsit_' function prefixe
*) Convert iscsi_target_device.c to use 'iscsit_' function pref
*) Convert iscsi_target_seq_pdu_list.c to use 'iscsit_' functio
*) Convert iscsi_target_datain_values.c to use 'iscsit_' functi
*) Convert iscsi_target_tmr.c to use 'iscsit_' function prefixe
*) Convert iscsi_target_nodeattrib.c to use 'iscsit_' function 
*) Convert iscsi_target_erl*.c to use 'iscsit_' function prefix
*) Convert iscsi_target_util.c to use 'iscsit_' function prefix
*) Convert iscsi_target.c to use 'iscsit_' function prefixes
*) Move iscsi_add_nopin into iscsi_target_util.c
*) Move iscsi_ack_from_expstatsn into iscsi_target.c
*) Drop needless iscsi_target_util.c wrappers
*) Move extern target_core_fabric_ops functions into iscsi_targ
*) Add comments for RX/TX nice usage and iscsi_release_commands
*) Convert TX thread to use schedule_timeout_interruptible
*) Fix potential NULL deference in iscsi_[free,stop]_session
*) Fix iscsi_np shutdown race
*) Drop iscsi_np->np_shutdown and ->np_state_lock
*) Remove dead iscsi_tpg_free_network_portals code
*) Remove remaining comment stubs
*) Convert cases to wait_for_completion*_timeout
*) Remove ad-hod debugging code

The changes from RFC-v2 -> RFC-v3 include:

*) Remove dead tpg shutdown code
*) Remove dead struct iscsi_np_ex logic
*) Fix up network portal handling
*) Rename core_* prefixed functions to iscsit_*
*) Convert semaphores to completion and mutex
*) Convert iscsi_global members to global variables
*) Cleanups for iscsi_target_login_thread logic
*) Use SIGINT in iscsi_handle_login_thread_timeout()
*) Cleanups for iscsi_thread_queue.c logic
*) Drop MOD_TIMER and SETUP_TIMER macros
*) Convert iscsi_index_t to use idr.h
*) Remove CONN* and SESS* deference macros
*) Update copyright and vendor
*) Fix up remaining struct semaphore callbacks
*) Renaming renaming non iscsi_target_* source files

The changes from RFC-v1 -> RFC-v2 include:

*) Drop extra crc32c_intel libcrypto magic from iscsi_login_setup_crypto()
*) Fix padded login response payload breakage from initial iscsi_proto.h
   conversion
*) Cleanups for iscsi_target_core.h and conversion a number of definitions
   to enums and inline defs
*) Removal of '__' prefix around u32 and friends
*) Other miscellanous checkpatch.pl cleanups
